Overhead bridge cranes, at auctions, sell either for outrageous money,
or for next to nothing. The reason is that, while expensive to order
and install, they are difficult to take down and built to suit a
particular building. So, unless there is an auction bidder who needs
this crane, there is no one to bid on them.

And here comes my thinking, I want to be able to bid on them and and
remove, economically and safely, for scrap metal.

I am talking about the "big ones", say 30 ton capacity and 60 feet
sapan, not little ones.

The $64,000 question is how to take them down.

I have a 30,000 lbs capacity forklift and a 11 foot boom for it, that
can be raised by forklift to about 11 feet, giving me about 22 feet of
vertical reach. I also have a number of smaller forklifts like 15,000,
18,000 etc.

What do you think, can I take down biggish cranes with it, if they are
say at the height of 20 feet?

I am not stupid and I can think of various possibilities and
attachments, however I also see that things can go very wrong at such
great heights and leverages.

Anyone seen this done?

Maybe add outriggers to the forklift?
